1. How do I remove (hide) the "PageID" from wiki pages.
I'm not certain I understand what you mean. To hide the PageID div class, the one that holds the NameSpace in a span above the
Table of Contents on the right-hand side of the default template:-
edit
userstyle.css and add:-
.dokuwiki .pageId {
visibility: hidden
}

2. How do I remove (hide) the "docInfo" information below wiki pages.
The same as for pageID, except the CSS is:-
.dokuwiki .docInfo {
visibility: hidden
}

3. How do I change colours of each individual components on the page.
Either using CSS in the
userstyle.css or the ones below in
style.ini (root of the template directory)
__background_site__ background colour of the whole site
__link__ colour of links
__existing__ colour of links to existing internal pages
__missing__ colour of links to missing internal pages
